Alnico magnets are comprised of Aluminium (Al), Nickel (Ni) and Cobalt (Co) together with small amounts of Iron, Copper and, occasionally Titanium. Alnico magnets are one of the oldest members of the magnet family and have been in existence for approximately 50 years. They are not as strong as Neodymium or Samarium Cobalt magnets but they are very stable over a wide temperature range and have a high magnetic flux density.

Alnico rods are good electrical conductors because of the metallic composition. When rods (diameter smaller than thickness) are being used for open circuit applications the thickness should be approximately 5 times the diameter. However, because they are course grained they are hard and brittle and must not be drilled, conventionally machined or used as structural components.

Extra care must be taken with these magnets because they can be partially demagnetised by allowing like poles to come into contact.
